[Can't decide zv3 or preorder zv4]

The prototype 12" Z4 has a single saz 3500 on it. The 1500v2 will be great for a pair of sa subs. The x,z, and ns line needs a 2500, 3500 or a ns-1 to power them.

[Differences between X AND Z SUB]

The x line is a brand new line. Subs range from 8"-18" and are on Pre order until April the 15th. The 8" isn't quite ready for Pre ordering yet. The Rms ratings are 750-1750 and will be more on the lines of a sq sub. The Z4's will handle 2000-2500w, have more excursion, and the enclosures will be a slight bigger than the other lines.

Great news to hear!

[Amp for 2 SD2-12's]

4 8ev3's on a saz 1200 will be loud in that truck. A set of the 6.5cs on a 125.4 running active. The big 3 kit from audio Technix along with 4ga and 8 ga kits ofc of course and a 270a alt would diffently do the trick.

[Just ordered 2 E8 v.3 D4 ... need some advice!]

Subs up port back would work too. 2 cubes net tuned to 35hz

[4 Sundown 8" SA v2 woofers box specs??]

I'm lookin to get 4 of these sundown sav2 8's. I really wanna drill the lows but wondering about cubic ft for all 4..? Any suggestions? Probably tuning Around 33 or 34 hz.

Thanks

4 cubes net will be fine for the 8"s . Those subs will surprise ya!

[2 SA-12 Enclosure Quick Check for 2500 RMS Daily]

Break them in properly and you won't be disappointed at all, nobody believes all I have is 1 12 in my trunk, can't imagine what 2 with 2500 watts to them will do!

Wow man you got me so excited I haven't had nice subs for 8 months now, and they were in a horribly designed sealed box, so holy shit i"m happy, how would you break them in? keep the power lower for a bit?

Breaking in a sub takes roughly two weeks. Crank it up at times for two weeks and you'll be fine. They can take a 1500 or a 2500 with no problem.

[2 sa 12s need to find a good amp to push them had a mtx 81000d on them but wasn't happy]

Sundown audio 1500 or a 2500 will be fine on a pair of Sa 12's
